MIMO-NOMA in Heterogeneous Network for 5G System

Non-orthogonal multiple access (NOMA) is the advanced technique that is now commonly used for 5G and beyond. In NOMA, within the same time and resource block, numerous users can be entertained, due to which high connectivity, low latency, and better spectral efficiency can be achieved. This feature of NOMA makes it superior to all the orthogonal multiple access (OMA) techniques. In this article, we have done the literature review and presented the research gaps for the MIMO-NOMA heterogeneous network (HetNets). We have also proposed a system model that does not incorporate Successive Interference Cancellation (SIC). Moreover, we have performed the outage probability simulation for the MIMO-NOMA heterogeneous network based on Monte Carlo simulations.
